IPC: H04N9/64
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To remove an MPEG ringing noise artifact by providing an anisotropic diffusion filtering means for selectively suppressing plural signal edge components having plural values less than a threshold value. SOLUTION: An MPEG data stream compressed by an encoder 1 is sent through a transmission channel 5 to the destination. When this data stream is received at that destination, it is decoded while using an MPEG decoder 9. In the case of processing these blocks composed of plural picture elements supplied in a raster scan format, an anisotropic diffusion filter 13 decides an edge significant threshold value for each block, decides a conduction value, generates an anisotropic diffusion on that block for smoothing a change and removes the ringing noise artifact less than a threshold value while preserving or improving features exceeding the threshold value. The block is passed through the anisotropic diffusion filter 13 and applied later to a display as high-quality digital video.

Title: Pull-up voltage supply method
IPC: G06F1/32
Filed: 1991-10-25
Abstract: PURPOSE:To reduce the power consumption of an apparatus with a microcomputer by turning on a gate circuit by an output port to supply a pull-up voltage only during the period when it is necessary for an input port to read an input signal by the instruction of a central processing unit. CONSTITUTION:When a central processing unit 1 instructs an output port 3 to turn on a transistor Q, the TR Q as the gate circuit is turned on, and a pull-up voltage Vp is supplied, and respective input terminals of an input port 2 are stabilized to low and high levels corresponding to turning-on/off of switches S. Low and high levels of terminals of the input port 2 are read. Next, the output port 3 is instructed to turn off the TR Q. At this time, the pull-up voltage is outputted and a current flows only in the period when this voltage is necessary, but the pull-up voltage is not supplied and the current does not flow in the other period; and therefore, the current consumption due to the pull-up voltage is reduced.

Title: Television signal processing method
Inventor: INOUE HIDEO
IPC: H04N11/14
Filed: 1991-10-25
Abstract: PURPOSE:To prevent production of vertical foldover distortion to obtain a smooth movement reproduced video image by applying band limit to a time axis and a vertical axis through the arithmetic operation of inter-field and inter-scanning line in advance at a sender side. CONSTITUTION:An interlace scanning television signal is generated by using only one frame in two frames of sequential scanning television signals. In this case, let number of frames of the inputting sequential scanning television signal be 60 frames per second, the maximum frequency response in the time axis direction sent by the television signal is 30Hz. After the band limit is applied to the time axis so that the frequency response of the sequential scanning television signal in the time axis direction is 15Hz or below, the interlace scanning signal is obtained. Since the highest frequency in the time axis direction capable of being sent is 15Hz by applying processing to interleave one frame from two frames, then reflection distortion is eliminated by applying time axis direction band limit to the signal before interleave processing.
